tancat802.1AD have small MTU value
Descripció
802.1Q allows to me for use MTU value over 1500 on fragment and network functions normally, transperent. But in 802.1AD this value is 'jammed' on 1430 for me, I tested this with 'ping -s'
Thus, the network doesn't work between two nodes connected over ethernet. I just backed to 802.1Q in config files.

I agree that removing VLANs is better, we had a discussion on libremesh mailing list where there was a problem with a specific device

Hi Pedro,
Thanks for your comment and the links. Yes, using different VLANs for the routing protocol[s] was cool back when all interfaces were physical (eth0, eth1...) but started to become a mess with eth0.1 and so. 802.1ad VLANs was a good attempt, but drivers support was varied and mostly bad.
I took the decision of not using VLANs (neither 802.1q nor 802.1ad) for routing by default, as you can see in http://dev.qmp.cat/projects/qmp/repository/revisions/a9e636957d1d5b333759e9e647590a6f51d2ae3f . So, I guess, from qMp v5.0 on, they won't be there anymore.
